Power station valve research and manufacturing

Center line-type butterfly valve

Center line-type butterfly valve is usually used for temperature ≤120℃, nominal pressure ≤ 1 6mpa water supply and drainage, gas pipeline for flow regulation and cut off the role of the fluid

Application
Center line-type butterfly valve is usually used for temperature ≤120℃, nominal pressure ≤ 1.6mpa in electric power, petroleum, food, medicine, chemical industry, textile, paper and other water supply and drainage, gas pipeline to adjust the flow and cut off the fluid role.
Characteristic
• The structure of the midline butterfly valve is characterized by the stem axis, butterfly plate center, body center in the same position; Sealing materials for rubber, ptfe and other materials;
• Novel design, reasonable, unique structure, light weight, opening and closing speed;
• Butterfly valve operation torque is small, easy to operate, labor-saving dexterity;
• Small size, light weight, small installation space, low cost, can be installed at any position, easy maintenance;
• Seals can be replaced, reliable sealing performance to achieve two-way sealing zero leakage;
• Valves can be clipped or flanged;
• Drive mode is worm gear drive, manual, pneumatic or electric.
